Description
(54) ЭЛЕКТРОПРИВОД ПАЛЬЦЕВ ИСКУССТВЕННОЙ КИСТИ(54) ELECTRIC DRIVE OF FINGERS OF ARTIFICIAL BRUSH
Изобретение относитс к медицине, а именно к протезированию и протезостроению и касаетс искусственных кистей с электроприводом , предназначенных дл протезировани инвалидов.The invention relates to medicine, namely to prosthetics and prosthetic design, and concerns artificial electric brushes intended for prosthetics of persons with disabilities.
Известен электропривод пальцев искусственной кисти, содержащий электродвигатель , упругую муфту, зубчатый редуктор, винтовую передачу и механизм самонастройки 1 .Known electric fingers of an artificial brush, containing an electric motor, an elastic coupling, a gear reducer, a screw transmission and a self-tuning mechanism 1.
Однако использование самотормоз щихс винтовых передач в известном электроприводе повышает энергозатраты и не обеспечивает достаточную надежность схвата.However, the use of self-braking screw gears in a known electric drive increases energy consumption and does not provide sufficient reliability of the gripper.
Целью изобретени вл етс повышение надожности схвата протеза и снижение энергозатрат .The aim of the invention is to increase the need to grip the prosthesis and reduce energy consumption.
Дл этого механизм самонастройки включает в себ входной вал зубчатого редуктора две параллельно расположенные ступени зубчатого редуктора, пр мой и обратный толкатели, промежуточное звено и ведомый вал. Причем ведущие шестерни ступеней неподвижно закреплены на входном валу зубчатого редуктора, а ведомые колеса ступеней подвижно соединены с ведомым валом.For this, the self-tuning mechanism includes the input shaft of the gear reducer, two parallel steps of the gear reducer, the forward and reverse followers, the intermediate link and the driven shaft. Moreover, the driving gears of the stages are fixedly mounted on the input shaft of the gear reducer, and the driven wheels of the stages are movably connected to the driven shaft.
Между промежуточным звеном и одним из ведомых -колес расположена пружина сжати .Between the intermediate link and one of the slave wheels, there is a compression spring.
На чертеже изображена кинематическа схема электропривода пальцев искусственной кисти.The drawing shows the kinematic scheme of the electric drive of the fingers of an artificial brush.
Электропривод пальцев искусственной кисти содержит электродвигатель 1, соединенный через упругую муфту 2 с зубчатымThe electric fingers of an artificial brush contains an electric motor 1 connected through an elastic coupling 2 with a gear
редуктором 3, на выходе которого находитс выходна передача 4. Кроме того, электропривод содержит механизм самонастройки, включающий две параллельно расположенные ступени 5, 6 зубчатого редуктора 3, пр мой и обратный толкатели 7, 8, промежуточное «звено 9, укрепленное на ведомом валу 10 телескопически. Ведущие шестерни 11, и 12 ступеней 5, 6 неподвижно закреплены на входном валу 13 зубчатого редуктора 3, а ведомые колеса 14 и 15 ступеней 5,gearbox 3, the output of which is output gear 4. In addition, the electric drive contains a self-tuning mechanism, including two parallel-spaced stages 5, 6 of the gear reducer 3, forward and reverse pushers 7, 8, intermediate link 9, mounted on the driven shaft 10 telescopic. Leading gears 11, and 12 steps 5, 6 are fixedly mounted on the input shaft 13 of the gear reducer 3, and the driven wheels 14 and 15 steps 5,
6 подвижно соединены с ведомым валом 10. Между промежуточным звеном 9 и ведомым колесОМ 15 расположена пружина 16 сжати . Электропривод работает следующим образом .6 are movably connected to the driven shaft 10. Between the intermediate link 9 and the driven wheel 15 there is a compression spring 16. The drive works as follows.
